abstract = "The title compound, [Cu(C9H13N5O2)(CH4O)](NO3)(2), consists of square-planar cationic complex units where the Cu-II centre is coordinated by an N, N, O-tridentate pyridoxal aminoguanidine Schiff base adduct and a methanol molecule. The tridentate ligand is a zwitterion exhibiting an almost planar conformation. The dihedral angles between the mean planes of the pyridoxal ring and the six-and five-membered chelate rings are all less than 2.0 degrees. The charge on the complex cation is neutralized by two nitrate counter-ions. Extensive N -H center dot center dot center dot O and C -H center dot center dot center dot O hydrogen bonding connects these ionic species and leads to the formation of layers. The pyridoxal hydroxy groups are the only fragments that deviate significantly from the flat layer structure; these groups are involved in O-H center dot center dot center dot O hydrogen bonding, connecting the layers into a three-dimensional crystal structure.",
